Flights from Istanbul to Heathrow: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew the route from Istanbul to Heathrow 
Verified travelerFlew with Turkish AirlinesAug 2026
Give plenty of time. The airport is huge with large amount of walking. Additional security checks at gates which are understaffed add to line ups and wait times.
CharlesFlew with American AirlinesMar 2026
Recommend you finding another airport for a connection. London Heathrow security process is laborious and very tiring.
EmreFlew with Turkish AirlinesSep 2024
Do not book the flights to Heathrow as they are star allience joint flights there are a lot of issues with the check-in and transfer documents are not checked in Turkey so there is a huge wait time problem during the border control due to this. It takes approximately 15 minutes for someone to go through checks because of this and if you are back at the que after the flight this issue costs you 2 hours wait time at the airport.
